Hi! First, sorry if this message is not threaded correctly. I am sending it with gmail and beng new to gmail, I haven't figured out yet how to make it inject the correct In-Reply-To header. Second, I did some simultaneous open tests myself, and succeeded making such a connection between varoius NAT-ed and firewalled hosts. Including two winows PCs both behind a linux router using iptables. One was running OpenWRT 1.0 (linux 2.4.30) and the other was a Linksys WRT54GL running some version of linux too. I took a few tries (manually running "nc --local-port X remote.host remote_port") that always succeeded in like five seconds. The routers were out of the box, that is the deafult iptables configuration for NAT.
